✦ Synopsis

Theaimof thepresent studyistodevelopa method forfollowing the changes in the chemical composition OF volatile substances released by plants. Dynamic headspace enrichment,followed by on-line thermal desorption and cryotrapping was coupled with capillary gas chromatography. The technique was optimized by adjusting the sampling and desorption parameters and by designing a special condensing device to avoid the transfer of excessive amounts of water into the analytical column. Details are given for the characterization of volatiles compounds released by mosses.
